Visibility of temporal blur on a gaze-contingent display

The spatio-temporal characteristics of the human visual system vary widely across the visual field. Many studies that have investigated these characteristics were limited to the use of artificial stimuli, such as flickering sinusoidal gratings, etc. Here, we present a gazecontingent system that is capable of modulating the spatio-temporal content of a high-resolution image sequence in real-time. In a first experiment, we measure - as a function of eccentricity - how much the temporal resolution of a natural video can be reduced before this manipulation becomes visible.
